Introduction

With this detailed step-by-step guide, you can easily replace your Galaxy S9+ display at home.

A replacement is necessary when the glass is shattered, the touchscreen does not respond to touch anymore, or the display remains black or flickers. During this repair, we replace the entire display unit including the frame, not just the broken screen. You may have to take some small parts from the old display unit, depending on how the new spare part is equipped.

The repair is a bit difficult as the Galaxy S9+ has to be opened via the glass backcover. Unfortunately, this is a rather cumbersome procedure, so plan enough time for it.

Do a backup before the repair, use a clean work surface and reserve enough time. If you are stuck at any point, just contact our live chat or write a comment on the corresponding step.

Getting started

32 steps
  1. Switching off your device

    Galaxy S9+ - Switching off your device 01
    Galaxy S9+ - Switching off your device 02
    1. Turn off your device by holding down the power button until the “Power off” option appears.
    2. Use your finger to confirm that you want to shut down your Galaxy S9+ and wait until the screen goes blank.
  2. Removing the back cover

    Galaxy S9+ - Removing the back cover 01

    Galaxy S9+ - Removing the back cover 03
    Galaxy S9+ - Removing the back cover 04
    Galaxy S9+ - Removing the back cover 05
    1. The back cover’s really glued to the chassis. Heat the device evenly with hot air to soften the glue. A temperature of 60 - 80°C should be sufficient. As a rule of thumb, you should still be able to touch your device without it being uncomfortably hot.
    2. The easiest way to loosen the back cover is to use a flat and flexible tool such as the iPlastix or iFlex. You will also need several picks to unstick the back cover all around.
    1. Heat the spot where you start and place a flat tool between the back cover and the frame.

    The iPlastix is made of plastic, so it won't scratch the device. On the other hand, it's very soft and tricky to insert.

    Be extra careful, the back cover can break very easily. If necessary, apply the heat several times and try again. Removing the back cover might take half an hour. Take a little more time and work carefully to make sure you don't break anything.

    1. Once the tool is inserted, stick a pick into the gap to keep it open. Then run the tool around the entire edge to gradually loosen the glue.
    2. Then heat the next part and insert the picks one by one.

    The back cover glue is extra strong on the lower edge.

    1. Once the back cover is loosened, lift it very slightly. The fingerprint sensor underneath the camera is still connected with a cable.

    Use a suction cup to lift the glass if you can’t find anywhere to insert the tool

  3. Disconnecting the fingerprint sensor

    1. After detaching the back cover, carefully lift it and disconnect the fingerprint sensor using the spudger.

    Galaxy S9+ - Removing the battery 01
    Galaxy S9+ - Removing the battery 02
    Galaxy S9+ - Removing the battery 03

    The battery glue is very strong, so you should use hot air again.

    Never heat the battery directly and don't bend it.

    The battery is glued around the outer edges but not at the center.

    1. Apply the hot air from the display side.
    2. We recommend running a flat tool, such as the iFlex, all around the battery.
    3. Now take out the battery.
    Be careful not to damage the battery. Take your time and heat the glue several times.

    4. Then set the board aside in a safe place.
    There's a small plastic pin in the opening of the SIM tray. Make sure it doesn't fall out.
